How do I log in to raise a ticket through my Support?

I know if may sound odd but I have tried following the various links that have recently been sent out advising me that the Brassring on Cloud support has now moved to a new service. But none of them work.

When I go to log in I get a "yikes" response advising me to clear cookies and reload - which is an endless loop.

It seems I can't log a ticket about the website not working either - because that route leads me to the same loop.

Has anyone had any success logging tickets on the new system for Brassring on Cloud?
